Abstract

The invention provides a distributed webpage downloading method and system. The method includes the steps that a web crawler sends a webpage downloading request to a task scheduling service unit; the task scheduling service unit receives the webpage downloading request and stores the webpage downloading request into a first information queue; an internet client obtains the webpage downloading request from the first information queue of the task scheduling service unit, downloads corresponding webpage data, and stores the webpage data into a second information queue of the task scheduling service unit; the task scheduling service unit feeds the webpage data in the second information queue to the corresponding web crawler requesting webpage downloading. On the basis of a point-to-point distributed webpage downloading mode of the two information queues, webpages can be captured by means of internet machines distributed in different places, webpage downloading requests can be responded accurately in real time, and limitations to concurrence downloading requests of websites can be effectively broken through.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a distributed web page downloading method and system. Background technique [0002] The distributed web page download system includes multiple web crawlers, and each web crawler needs to grab web page data from the Internet and save it. All these web crawlers may be distributed in different geographical locations. According to their different degrees of dispersion, web crawler systems can be divided into two categories: one is a distributed web crawler system based on a LAN; the other is a distributed web crawler system based on a wide area network. type web crawler system. [0003] In web crawling projects, IP address resources are usually the most lacking. Most websites, especially in specific fields, such as Weibo, etc., will impose restrictions on the crawling end, such as the concurrent request limit of the same IP address, a period of time The number of...
